Installed Microsoft Internet Explorer Without Internet Mail

Reinstall Internet Explorer and install the Internet Mail component.

Windows 98 Installed and Uninstalled

To resolve this issue, see the "Internet Mail and News for Internet Explorer 3.02 Does Not Work" section of the following article in the Microsoft Knowledge Base:

There Is Not Enough Free Space on Your Hard Disk

If there is not enough free space, you may receive "Unable to start the program" or "Riched32 failed to load" error messages, followed by "this note could not be displayed due to an initialization error."

To resolve this issue free enough space on your hard disk for the swap file to be allocated properly.

For additional information, click the article number below to view the article in the Microsoft Knowledge Base: WAB files are stored in the Windows folder with a name of user name.wab, where user name is your logon name. If this file becomes damaged, or if the format of the file is changed, it no longer matches the version of the Wab32.dll file and Internet Mail and News is unable to run. The WAB file and the Wab32.dll file must be from the same version of Internet Mail and News.
